Justification:
Listed as Data Deficient as it is known only from two localities, with the last confirmed reports of this species are from the 1970s. No information is available about biology and population status.

The species occurs in the Luzon Faunal Region and is apparently endemic to central and northern Luzon Island (Laguna and Mountain provinces) in the Philippines (Heaney et al. 1998; Musser 1982). It is known only two localities: a high elevation pine forest at 2,250 m on Mt. Data in the Cordillera mountain ranges and a rice field at 75 m in Laguna province (near the International Rice Research centre).

This species is only known from only two individuals, the one from the rice field in Laguna province, the other from Mt. Data, on the Cordillera mountain range (L. Heaney pers. comm.). Despite repeated trapping in the areas with different bait and trapping techniques, no additional individuals have been found.

The species was taken in densely vegetated gullies in pine forest at about 2,250 m (Rabor 1955; Rabor 1986; Sanborn 1952) and in a rice field in the lowlands at about 75 m (Barbehenn et al. 1973; Musser 1982). Nothing else is known about the species biology or natural history, but the individual's occurrence in the rice fields may suggest that it is able to tolerate some level of disturbance. The species dentition indicates also it might be associated with bamboo (L. Heaney pers. comm.).

No major threats are known, but it is likely that the species would be affected by conversion of forest into agricultural lands in the Cordillera mountain region, and into human settlements in Laguna (L. Heaney pers. comm.).

The northern record is from Mount Data National Park, which aside from about 86 ha continguous mossy forest patch, and has been largely converted to farm land with high value vegetable crops. However, there is extensive suitable habitat in the area (L. Heaney pers. comm.). Further studies are needed into the distribution, abundance, reproduction and ecology of this species.
